摘　　要：考虑（ｅ，２ｅ）出射电子动量相关效应及交换影响，对Ｈ（１ｓ）原子靶推出了三重微分散射截面（ＴＤＣＳ）明晰表达式。计算了入射电子能量为１５０ｅＶ，电离电子能量分别为３ｅＶ，５ｅＶ，１０ｅＶ情况下共面及非共面ＴＤＣＳ，结果与实验值符合较好。Considering the momentum correlation and role of exchange of eject electrons, we investigate the electron impact ionization of atomic hydrogen in a coplanar and non-coplanar scattering geometty. The results are better than those of Born approalmation, particularly for fixed scattering angle, the larger momentum transfer, the better the results.
